RESUMOEste estudo teve como objetivo, avaliar a sobrevivência e o crescimento inicial de sete espécies arbóreas nativas na restauração ecológica de florestas ciliares no entorno de nascentes na região Sul de Minas Gerais. As espécies estudadas foram Trema micrantha (Cannabaceae), Guazuma ulmifolia (Malvaceae), Lithraea molleoides (Anacardiaceae), Cedrela fissilis (Meliaceae), Aspidosperma parvifolium (Apocynaceae), Machaerium villosum (Fabaceae) e Handroanthus serratifolius (Bignoniaceae). O experimento foi realizado em delineamento inteiramente casualizado, em esquema fatorial 7 × 3 (espécies × sítios). Onze meses após o plantio verificou-se que, com exceção de C. fissilis e de M. villosum, todas as espécies apresentaram taxa média de sobrevivência igual ou superior a 80%. A espécie que apresentou menor crescimento médio em altura após os onze meses foi C. Fissilis (9,27 cm). Com exceção dessa espécie, todas demonstram capacidade em se estabelecer neste tipo de ambiente e são recomendadas em projetos de restauração ecológica de florestas ciliares nessa região. PALAVRAS-CHAVE: Enriquecimento de florestas tropicais, florestas ripárias, recuperação. ABSTRACTThis study aimed to quantify the survival and early growth of seven native tree species in ecological restoration of riparian forests in the vicinity of springs in the Southern region of Minas Gerais. The species used were Trema micrantha (Cannabaceae), Guazuma ulmifolia (Malvaceae), Lithraea molleoides (Anacardiaceae), Cedrela fissilis (Meliaceae), Aspidosperma parvifolium (Apocynaceae), Machaerium villosum (Fabaceae) and Handroanthus serratifolius (Bignoniaceae). The experiment was carried out in a completely randomized design, in a factorial 7 × 3 (species × locations). Eleven months after the plant it was found

Rupestrian complexes of the Serra do Espinhaço are recognized for their high degree of biodiversity and endemism. However, environmental impacts, particularly from mining, have degraded these environments. Th e purpose of this study was to describe the herbaceous-subshrub communities that occur in quartzitic (QRC) and ferruginous (FRC) rupestrian complexes in diff erent seasons of the year, with regard to fl oristic similarity and phytosociological structure. Additionally, the study aimed to identify native species with potential use for the restoration of similar degraded areas. Vegetation was sampled from plots located in the municipality of Conceição do Mato Dentro, state of Minas Gerais. Five contiguous strata of 10 × 50 m were demarcated in each environment, in which 12 plots of 2 × 1 m (2 m²) were randomly distributed, for a total of 60 plots (sample units) in each physiognomy. Th e studied communities exhibited few similarities and lower fl oristic diversity than other rupestrian complexes. Detrended correspondence analysis distinguished the communities of FRC from those of QRC. Th e species with the highest value of importance in FRC were Bulbostylis fi mbriata and Centrosema brasilianum, while in QRC Echinolaena infl exa had the highest values, thus, making them eligible for restoration programs in similar environments.
